I underpaid my California estimated taxes for 2024 because I used TurboTax to generate the estimates, and they were clearly too low, despite the fact that I rounded the estimates up to the nearest $100. I did *not* have this problem with Federal estimates.
There's a bug in how TurboTax is calculating CA 540-ES. I am seeing others posting here with this same problem. Because of this, I received a penalty of $110 from California. Is this a known problem? Is anyone working on fixing this?
